Basically the main things for growing MJ outdoors are to...
-Water it when the soil is touch dry (dip your finger in - if it's dry approx an inch deep then water)
-Give it fertilisers with most amount of Nitrogen (N) (nutrient packed usually have N-P-K written on them ... Do not give them nutrients now, wait till they are atleast 3-4 weeks old
-Since its outdoors you dont need to worry about sunlight which is a good thing..so just let it grow naturally....
-You will probably need to transplant it into a bigger pot IF it's actually in a pot...if it's in the ground then you have nothing to worry about.
-When it starts to flower (although im probably getting a bit ahead of myself

) give it nutrients with the most amount of Phosphate and least Nitrogen...
How's the weather where you live?
What season are you in?
Hope this helps a wee bit
